Software Features (BrinSoft)

This is precise Brinell Impression Measurement Software. High technology image management system is built to get desired accuracy with IS compliance to be measured within given time.

The detailed features are as listed below:

Precise Brinell Impression Measurement

Based on Image Processing techniques, BrinSoft achieves high precision image measurement and also the repeatability in the readings. It is easily configurable for environment. Working with USB camera enables BrinSoft to be deployable at difficult measuring conditions along with standard BIMS applications.

Measurement Modes

There is a fast and accurate Auto mode for standard components with good surface finish. Additionally, a Semi-Auto mode is provided for measuring blured images due to poor surface finish. In case of very fast measurement requirements where the actual hardness value is not required. A confirmation that it is within specified limits is enough, compare mode is also provided. With such variety of modes, most of the test conditions are covered enabling the user to obtain results in required methodology and in required formats.

Calibration Facility

Calibration is the heart of every measurement. So, BrinSoft provides multiple calibration levels to achieve high accuracy in results. There is Pixel calibration accompanied with multi-point calibration and ERMA calibration. With these calibration techniques, BrinSoft provides precise measurement results.

Analysis And Reporting

If one cannot find the historical data, it is as good as unavailable. So, Search is key feature of BrinSoft. Test Certificate and Customer are key search criteria along with other details. Uniqueness of the Test Certificates being generated is maintained and the same is available for searching and printing.

Additionally, there is statistical analysis available in tabular and graphical formats to assist the user.

Hardware Interface

The key input to BrinSoft is the image captured by the CCD camera. So, presently it is configured to work with special purpose USB camera for this application. However, it can be easily configured to work with any other camera considering the image quality.

Portable Rockwell Hardness Testers (Model: MRP-1 )

• Hardness tester is quite handy for product testing of crank shafts, cylinder blocks, liner & assemblies.
• Can also be used for testing the hardness of both inside & outside of surface testing of pipes, bushings, ball bearing rings or other complicated parts.
• The model can be used in any direction without affecting the accuracy.
• Maximum test height x throat is 110 x 55 mm.
• Rockwell hardness scales such as HRA, HRB, HRC, etc. is obtained by using different types of indentors ( Diamond / Ball ).
• Machines strictly conforms to IS:1586- 2000 for Rockwell test.

The Webster Hardness Testers are a portable, fast, accurate hardness gauge that are made in three distinct models for testing Aluminum, Brass, Copper and Mild Steel. Webster Hardness Testers will quickly identify tempers and test a variety of shapes that other testers cannot check, such as extrusions, tubing and flat stock.

All testers operate in the same manner but differ only in penetrator design, type of load spring and hardness ranges. The principle of operation is simple. The work to be tested is placed between the anvil and the penetrator. Pressure is then applied to the handles until "bottom" is felt at which time the dial indicator is read.

Model B

The Model B Tester is designed to cover the hardness of aluminum alloys from the 100 to the 7075 series. The 20 graduations on the Webster dial indicator covers the range between 25 and 110 on the Rockwell E Scale.

Model B-75

The Model B- 75 Tester was developed to obtain more sensitive response to slight changes in the upper range of hardness covered by the Model B. This sensitivity is particularly useful in testing mild steel and the stronger aluminum alloys. For brass the B-75 covers the range from annealed to full-hard. This added sensitivity is accomplished by incorporating a penetrator of slightly different contour and a heavier load spring than used in the Model B. The 20 graduations on the Webster dial indicator covers the range between 20 and 100 on the Rockwell B Scale.

Model BB-75

The Model BB-75 Tester was developed to answer the need of certain industries for a method of rapidly testing the hardness of electro-deposited copper in the low hardness range. The B-75 penetrator is used to give sensitivity, and the Model B load spring is employed to give light pressures. This combination allows the user to test the soft range of many common materials. The graph below shows the range covered by the Model BB-75 tester on copper.

Applications and Features

Applications for Webster Hardness Testers are:

• Identifies heat-treated from nonheat-treated parts.
• Provides correlation between a bench mounted hardness tester and the production line.
• Segregates materials in stock.
• Differentiates between soft or work-hardened material.
• Identifies parts made from improper or substandard alloys.
• Checks for proper heat-treatment response.
• Useful in conjunction with stationary laboratory hardness testers. Gives a rapid 100% check on parts which would consume many man hours with slower operating test equipment.
• Can be used on assemblies that cannot be brought to the labs.

Webster Hardness Testers Feature:

• One hand operation and portability.
• Round 3/8 inch diameter anvil permits testing a great variety of shapes.
• Simple operation permits readings independent of the operator's skill.
• Test is made by simply applying pressure to the handles until "bottom" is felt.
• Easy-to-read dial indicator with 20 graduations permits use of the tester as "go" and "no-go" gauge.
• Standard hardness gauge tests materials up to 1/4 inch in thickness.
• Increased capacities available up to 1 inch.

These Hardness Testers are used to Test the Hardness of Steel, Steel castings, Cast Iron, Forgings, very large components, etc.

The Shore Hardness is defined as the resistance to penetration by an indenter of specified shape under a defined load.

Shore Hardness tester are available in various models for testing Vulcanized Rubber, Plastic, Ebonite, Fibre and all other soft and Hard Elastomers as per latest American Std ASTM-D 2240 and German Std DIN 53505.

Shore A are suited for use on soft elastomers the hardness of which is between 10 and 90 Shore A. Shore D are suited for use on harder elastomer(hardness >80 Shore A) and on plastics the hardness of which is between 30 and 90 Shore D.
